There's a bit of controversy about whether data can say where people actually catch coronavirus . According to Public Health UK 'common exposure data does not prove where people are contracting covid-19.It simply shows where people who have tested positive have been in the days leading up to their test and it is used to help identify possible outbreaks' . Which is all well and good but wasn't similar data was used to justify closing pubs, cafes and restaurants?
Such figures were wheeled out in the face of demands for strong evidence, but the evidence requested doesn't exist. Nor in my book does it need to exist in order to justify the approach to pubs and restaurants. Weaker evidence combined with no-brainer concepts about respiratory viruses is all that is required....
The risk is there anywhere that people mix. The risk is worse when people are indoors. Household transmission is the worst offender, but since households cannot be closed, the sources of the virus getting into a member of that household in the first place is the area to target. Hospitality is an obvious vector and in some ways its low-hanging fruit, because such locations can actually be closed, whereas much less can be done for other known risks such as working and health and social care, we can't just stop doing those other things.
For me the combination of basic facts about respiratory viral transmission and some data we do actually have showing increased risks for those who work in hospitality is more than sufficient evidence to justify closing hospitality, and I do not think more is required just because such closures are distressing to some people. Plus I strongly suspect that even if strong, direct evidence was presented, those who dont want to come to terms with these facts will then just quibble about the percentage. 'Only 7.5% (my made up number) of cases come from pubs' I can almost hear them crying now. To which my response would be, that's a fair chunk of the pie and justifies the closures. Numbers like that would just indicate to me that other settings need to be closed too, not that pubs had been unfairly targeted. I also look at what most other countries feel compelled to do and the similarities are obvious, hospitality is almost always part of the mix and results are achieved when these things are closed in combination with other measures.
Behind the scenes, this is the sort of things SAGE were saying in September when they were looking at the next required steps:
Household transmission remains the most widely recorded setting of transmission. PHE reports secondary attack rates of around 40-50% within households, confirming the key role the household plays in transmission. Outside the household, preliminary analysis of a recent case-control study by PHE suggests that working in health and social care remains a risk factor, as is working in close personal services and hospitality. Activities associated with increased risk amongst cases include frequenting entertainment venues e.g. bars and restaurants. Outbreaks associated with restaurants and bars have also been recorded, both in the UK and elsewhere. Outbreaks in educational settings are leading to widespread disruption. It is still not clear to what extent (if any) schools magnify transmission in communities rather than reflect the prevalence within the community.
Thats a mostly fair summary of what it is reasonable to say without stronger evidence being available, and if I were a decision maker I would not hesitate to act on it. I am not interested in putting hospitality and close personal service workers at risk, and their customers, just because some people demand a stronger form of evidence than is available. Not that this would be my only focus, since I am also disgusted by the attempts to do education as normal, and by the falling rate of people working from home as demonstrated by another SAGE quote:
For example, ONS data show that rates of working from home are continuing to decline, from around 40% who “worked from home only” at the start of June, to 20% at the start of September.
Both SAGE quotes are from a September 21st paper.
